按钮背景透明未在 WPF 中设置

Question

WPF：我有一个按钮，图像是在 c# 后面的代码中设置的

 btn.Content = new Image
                    {
                        Source = new BitmapImage(new Uri(MasterVariables.applicationPath + "Normal.png")),
                        Stretch = Stretch.Fill,
                    };

现在的问题是，当按钮进入按钮时，背景颜色设置为蓝色，但我在 mouse_enter 事件中更改了图像

 btn.BorderThickness = new Thickness(0);
            btn.Style = (Style)FindResource(ToolBar.ButtonStyleKey);
            btn.Background = Brushes.White; btn.BorderBrush = Brushes.Transparent;
           btn.Content = new Image
                    {
                        Source = new BitmapImage(new Uri(MasterVariables.applicationPath + "Hover.png")),
                        Stretch = Stretch.Fill,
                    };

图像发生了变化，但是当鼠标移到背景上时，背景会以蓝色突出显示

Answer 1

更新您的样式以在 MouseOver 上触发背景：

<Style.Triggers>
    <Trigger Property='IsMouseOver' Value='True'>
        <Setter Property='Background' Value='White' />
    </Trigger>
</Style.Triggers>

Answer 2

试试这个

 <ControlTemplate.Triggers>
                            <Trigger Property="IsPressed" Value="true">
                                <Setter Property="Background" Value="Gray" TargetName="panel" />
                            </Trigger>
                            <Trigger Property="IsMouseOver" Value="true">
                                <Setter Property="Background" Value="LightGray" />
                            </Trigger>
                        </ControlTemplate.Triggers>
